The invention discloses an anti-torsion swing arm of an electric transmission unit. The anti-torsion swing arm comprises a connecting bracket and a bushing, the bushing is pressed on the connecting bracket in an interference manner; the connecting support is used for being connected with a transmission unit, and the lining is used for being connected with a vehicle body. Wherein the bushing is formed by adopting a reducing process and comprises an outer framework, an inner framework and a rubber main spring; the inner framework is installed in the outer framework, and the outer framework and the inner framework are vulcanized into an integrated structure through the rubber main spring. Auxiliary supporting and damping effects can be provided for the transmission unit, the movement range of a transmission unit system can be effectively controlled within a target range, abrasion of an output center gear on the electric transmission side is reduced, and product reliability is improved.
